Dealing with Dormancy: A Japanese Knotweed Case Study

As many PCA members are aware, dealing with Japanese Knotweed through herbicide application can only be considered a control measure, not a complete eradication programme, as there remains the risk of new shoots emerging due to factors that can include glyphosate-induced dormancy.

Indeed, dormancy can be triggered by the incorrect use of herbicides – which in turn can result in stunted growth – or in some cases no regrowth at all.

Is it feasible that the correct application of glyphosate can still result in placing an infestation into induced dormancy? Why is this and what evidence do we have to support the notion? 

In this guest blog for the Property Care Association (PCA), our very own Andrew Ford takes a closer look at this perceived phenomenon.
